### Editing the Overlay File
The overlay file can contain any of the values in the [Istio Operator spec.](https://istio.io/latest/docs/reference/config/istio.operator.v1alpha1/#IstioOperatorSpec) The overlay file included with the Istio application is just one example of a potential configuration of the overlay file.
As long as the file contains `kind: IstioOperator` and the YAML options are valid, the file can be used as an overlay.
